Many sudden (or instantonic) processes in nature, such as, e.g., crackling noise, exhibit scale-free statistics often called the Zipf's law. As an explanation for this peculiar spontaneous dynamical behavior, it was proposed to believe that some stochastic dynamical systems have a tendency to self-tune themselves into a critical point, the phenomenological approach known as self-organized criticality (SOC).[40] STS offers an alternative perspective on this phenomenon.[41] Within STS, SOC is nothing more than dynamics in the N-phase. Specifically, the definitive feature of the N-phase is the peculiar mechanism of the TS breaking. Unlike in the C-phase, where the TS is broken by the non-integrability of the flow, in the N-phase, the TS is spontaneously broken due to the condensation of the configurations of instantons and noise-induced antiinstantons, i.e., time-reversed instantons. These processes can be roughly interpreted as the noise-induced tunneling events between, e.g., different attractors. Qualitatively, the dynamics in the N-phase appears to an external observer as a sequence of sudden jumps or "avalanches" that must exhibit a scale-free behavior/statistics as a result of the Goldstone theorem. This picture of dynamics in the N-phase is exactly the dynamical behavior that the concept of SOC was designed to explain. In contrast with the original understanding of SOC,[42] its STS interpretation has little to do with the traditional critical phenomena theory where scale-free behavior is associated with unstable fixed points of the renormalization group flow.
It is well known that various types of transient dynamics, such as quenches, exhibit spontaneous long-range behavior. In case of quenches across phase transitions, this behavior is often attributed to the proximity of criticality. Quenches that do not exhibit a phase transition are also known to exhibit long-range characteristics, with the best known examples being the Barkhausen effect and the various realizations of the concept of crackling noise. It is intuitively appealing that theoretical explanations for the scale-free behavior in quenches must be the same for all quenches, regardless of whether or not it produces a phase transition; STS offers such an explanation. Namely, transient dynamics is essentially a composite instanton and TS is intrinsically broken within instantons. Even though TS breaking within instantons is not exactly due to the phenomenon of the spontaneous breakdown of a symmetry by a global ground state, this effective TS breaking must also result in a scale-free behavior. This understanding is supported by the fact that condensed instantons lead to appearance of logarithms in the correlation functions.[44] This picture of transient dynamics explains computational efficiency of the digital memcomputing machines.[45]
When her beloved grandmother passes away, Mia Broadhurst returns to the snow-covered seaside village of Winsted Cape, where Grandma Ruth ran the lighthouse overlooking the golden beach. This will be Mia's first Christmas without her, and she can't bear to part with the lighthouse that has been in their family for generations. As she steps into it, childhood memories rush back to her. She can almost hear them playing tag on the steps. But her life is back in New York, dedicated to a busy PR firm, and she has no choice but to sell. With the snow falling, turning the grounds into a winter wonderland, Mia works with real estate agent Will Thacker. As they restore the historical building, she tries not to notice how handsome he is. After all, she's only home for Christmas and Will's deep blue eyes, as stormy as the Atlantic Ocean, tells her he has his own heartbreak to contend with. Warmed by a crackling fire, Mia packs up Grandma Ruth's belongings with the help of her mother and sister. But waiting for them is a black-and-white photograph with a faded inscription. The mysterious message is the key to a family secret that has been hidden for decades - one that changes everything. When Mia finds out the truth, will it save the precious lighthouse and show Mia where her heart belongs? Or will it tear her from Winsted Cape - and Will - forever?
Almost everybody knows a little about electricity. Veryoften on a cold day, if one rubs his feet on a carpetand then touches another person, a crackling sound willbe heard, and the person touched will receive a shock.Something like this happens when a cat's back is rubbedbriskly. Despite these and other interesting thingsthat have long been known, not much interest was takenin electricity so that it was not until very recentlythat much was really understood about it. Men did notbegin to study electricity with care until about twohundred years before Washington became President.
For about a year after this, Bessemer was occupied with other things. But theidea of making a machine which in an hour would give to a pound of brass thevalue of an ounce of gold haunted him. With the aid of a microscope he studiedthe bronze powder he had bought, and that which he had made, and saw why hispowder was worthless. He then designed and made with his own hands a number ofworking models, one to cut the brass, another to roll the tiny particles,another to polish them, and finally one to sift the powder. "At last aftermonths of labor, the great day of trial once more arrived. . . .I felt that on the result of this . . . trial hung the whole of my future life's history, and so it did . . . Iwatched . . . with a beating heart, and saw the iron monsters do theirappointed work."
Most people would doubtless have been satisfied with sogreat a discovery and stopped. But to Bessemer'sinquiring mind, this question came: "Yes, pig iron can bechanged into steel by forcing air into the molten metalwhen fuel is used; but can steel be made in this way,without the use of fuel?" The answer to thisquestion changed the history of the world.
No wonder Bessemer has been called the"Captain of Modern Civilization," that his discovery is ranked with the printingpress and steam engine as one of the three greatest inventions in the history ofthe race, and that his fame is as wide as the world.
Morse was tempted many a time to give up. But the thought that his invention marked a new era in history, andwould improve the condition of millions of people, kept him from it. In the winter of 1843, he went once moreto Washington, seeking the aid of Congress. Columbus himself was scarcely more persevering underdiscouragement. On the day his bill passed the House of Representatives, Morse wrote to Mr. Vail: "For twoyears I have labored all my time, and at my own expense, without assistance from the other proprietors, toforward our enterprise. My means to defray my expenses, to meet which every cent I owned in the world wascollected, are nearly all gone. If the bill should fail in the Senate, I shall return to New York with thefraction of a dollar in my pocket." "Had the passage of the bill failed," he wrote to a friend, "there wouldhave been little prospect of another attempt on my part to introduce to the world my new invention."
"The first flight lasted only twelve seconds, a flight very modest compared with that of birds, but it was,nevertheless, the first in the history of the world, in which a machine carrying a man had raised itself by itsown power into the air in free flight, had sailed forward on a level course without reduction of speed, and hadfinally landed without being wrecked. The second and thirdflights (the same day) were a little longer, and the fourth lasted fifty-nine seconds, covering a distance ofeight hundred and thirty-five feet over the ground against a twenty-mile wind."
